Tom,
Thanks. If I can find a Linux based tool for updating the CMOS on these
supermicro nodes, then runimage seems the way to go. Oddly, supermicro
doesn't seem to have one.
Xiao, Jarrod,
Thanks, boottarget works very well once "os=boottarget profile=bprofile" are
set. Turns out its also well documented in wiki at
http://sourceforge.net/apps/mediawiki/xcat/index.php?title=BootTarget
There was one surprise. The node's "addkcmdline" attribute was appended to the
memdisk command line even after "addkcmdline" was set to a space at the node
level. So if addkcmdline is defined at a group level, the only way to prevent
it being appended is to remove the definition in the group. Hmmm, it might
also be possible to add another group with a blank definition earlier in the
group list. Didn't try that.
Thanks again,
Goran

Subject: [xcat-user] Netbooting off a floppy or CD image.
The following pxe boot file will boot a FreeDOS floppy disk image that runs a
CMOS utility (after memdisk and the image file are copied to /tftpboot):
[root@drdxcatmn1 xcat]# cat /tftpboot/pxelinux.cfg/develkv8
#run CMOS utility on FreeDOS
DEFAULT Floppy
LABEL Floppy
LINUX memdisk
APPEND initrd=xcat/floppy/cmos-settings.img
IPAPPEND 2
Is there a way to have xCAT generate a similar pxe file when needed? Say when
a "nodeset host netboot=smcmos" is run?
It looks like the boottarget table can help, but I may not be setting it up
correctly because "nodeset host netboot=smcmos" generates a missing kernel
error.
[root@drdxcatmn1 xcat]# tabdump boottarget
#bprofile,kernel,initrd,kcmdline,comments,disable
"smcmos","memdisk","xcat/floppy/cmos-settings.img",,,
[root@drdxcatmn1 xcat]# nodeset develkv8 netboot=smcmos
Error: Did you run "genimage" before running "packimage"? kernel cannot be found
Error: Some nodes failed to set up netboot resources, aborting
Also tried copying /tftpboot/memdisk to /tftpboot/xcat/netboot/smcmos/memdisk,
but no help.
Any suggestions?
Thanks,
Goran
